LAUNDRY APPARATUS.

Application'filed March 29, 1920. Serial No. 369,499.

To all whom it may concern:

Beit known thatI, HARRY O. BARTLETT, a citizen of the United States,residing at lVashington, in the District of Columbia, have inventedcertain new and useful Improvements in Laundry Apparatus, of which thefollowing is a specification.

My invention relates to washing apparatus, for laundry purposes, and hasparticular reference to such apparatus in the nature of an attachment,to be applied upon or used in connection with the ordinary stationarylaundry tub, while not necessarily restricted to this use.

An important object of the invention is to provide an attachment of theabove mentioned character, which may be installed upon the ordinarstationary laundry tub, without altering tlie construction of the tub,or injuring the same.

A further object of the invention is to provide apparatus of the abovementioned character, which is of simple construction, strong anddurable.

A further object of the invention is to provide means whereby themovable drum may be removed from the tub, without disturbing the drivingmeans or gears.

A further object of the invention 1s to provide a hanger bearin havingmeans to guide the trunnion of t e drum, upon its downward movement, andto also shift the drum longitudinally, whereby the drum will beproperlytconnected with its driving gear.

A further object of the invention is to provide means for locating andsupporting a motor, and associated elements, outwardly of or beneath theforward inclined side of the laundry tub, whereby these elements occupythis space and are protected or covered, and an upstanding driving shaftis properly located and may be employed to ad ustably support a wringer,in a proper position for coaction with the several compartments of thetub.

A further ob'ect of the invention is to' provide a mova le orrotatabledrum, having interior lugs or projections disposed in a peculiar manner,to prevent the clothes or laundry from being unduly tangled or knotted.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 15 designates anordinary stationary laundry tub,

supported by legs 16. This tub has a forward inclined side l'Z, as iscustomary, for

with the partition 18, preventing displacement of the strip. 22. Asclearly shown in Figure 2, a transverse head 24 is formed integralwiththe forward end of the strip 22, and contacts with the upper edge ofthe side 17, and serves as a brace to prevent the supporting frame fromturning on its axis. This head carries a vertical or depending flange25, preferably formed integral with the upper end of an invertedY-shaped member 26, embodying spaced vertical arms 27. At their lowerends, as shown in Figure 3, the arms 27 are bent inwardly forming hori-'zontal extensions 28, serving to support a platform 29, for a purpose tobe described.

The arms 27 are preferably reinforced by.

longitudinal ribs 30, whereby these arms are stitl'ened,.to preventvibration, and are T- shaped in cross-section.

At the upper end of the arms 27, is an inwardly bent or formed aperturedear 31, having connection witha section of a cable 32. This section ofcable isconnected with one screw-threaded element 33, of a turnbuckle34, the other screw-threaded element of which is connected with a cablesection 35, passed beneath the tub, as shown in Figure 3 and provided atits free end with an eye-bolt 36, arranged within an elongated slot 37in the free end of the strip 22. The bolt is therefore adjustablyconnected with this strip, whereby the cable may be employed in securingthe supporting frame to the tubs of slightly different widths.

The numeral 38 designates a housing or casing, preferably cast integralwith the strip 22 and head 24, at the forward end of the strip, andpreferably cylindrical. This housing is preferably vertically arranged,and has a cap 39, detachably see cured thereto by screws 40 or the like.

A depending bearing 41 is carried by the lower end of the housing 38,and receives therein a vertical combined driving and pivot shaft 42,having its lower end journaled in a gear casing 43, rigidly secured tothe platform 29, as shown. This gear casing encloses a worm wheel 44,rigidly secured to the shaft 42, and engaging a worm 45, upon a shaft46. Theshaft 46 is connected with the armature shaft 46', by a frictionclutch device, embodying a block 48', preferably formed of wood, andhaving a radial slot to receive the ends of these shafts. The block 48'is surrounded by a metallic band 49, having depressions 50 therein, andapertures 50, receiving a bolt 51', passing through the ends 52'. Btightening up the nut upon the bolt the clamping engagement upon theblock and shafts may be adjusted.

As clearlyshown in Figure 5, the verti cal shaft 42 carries a bevel gear48, rotatable thereon, and engaging a bevel gear 49, angularly arranged,and secured to a diagonal shaft 50, journaled through a bearing 51, nearits upper end. This diagonal shaft hasits lower portion slightlyreduced, as shown at 52, forming a shoulder 53. the reduced portion 52being journaled in a bearing 54, preferably formed integral With adepending arm 55, preferably integral with the strip 21, and flange 23.A bevel gear 56 is secured to the reduced portion 52, by aclamping screwor bolt 57, and this bodying an L-shaped head 64, to straddle the end ofthe tub, and be clamped thereto by a bolt 67. This hanger hearing, asshown more clearly in Figure 6, is provided with an interior groove 68,which is tapered, and

.decreases in width downwardly. The end of this groove terminates in abearing 69, and an inclined wall is arranged adjacent the bearing 69,and projects inwardly.

The numeral 71 designatesa drum as a whole, embodying heads 72, and aperiphery 73, including a removable cover 74, held closed by anysuitable means. This periphery may be formed of spaced slats. In Figure'17, slats 73', of a modified form, are shown, which are adapted to formthe periphery of the drum. These slats have perforations 74'. The slatsmay be opened at 74', in Figure 14. Arranged within the drum arelongitudinal agitator bars '75, four of which may be employed, as shown,and these bars may be diametrically arranged. Two of the diametricallyarranged bars have inwardly projecting extensions or lugs 76,equidistantly spaced from their ends, while one of the remaining barshas a corresponding lug 77 at one end, and the other 'bar has a lug 78arranged at the opposite end of the drum. The function of theseprojections or lugs is to prevent the clothes being washed, frombecoming.unduly tangled or knotted.

A coupling member 79 is suitably secured to one head 72, by screws orthe like, and is provided with a socket 80, polygonal in ycross-section, to receive the extension 61. A

coupling member 81 is secured to the opposite head 72, and carries atrunnion 83, which is cylindrical, and adapted to operate within thegroove 68. 'When the drum is lowered into the tub, the trunnion 83 maybe conveniently placed within the upper wide end of the groove 68, andthe extension 61 inserted within the socket 80, or its reduced end 62inserted therein. When the drum approaches the lowermost position, thetrunnion 83 contacts with the inclined wall 7 O, which shifts the drumlongitudinally to the right, whereby the extension 61 becomes gearcasing completely inserted within the socket 80. It is thus seen thatthe drum is connected with the gear 58 and will be driven by the motor47, through the medium of the interposed gearing.

As more clearly shownin Figure 5, a lever 83' is pivoted to the housing38, and projects therebeyond, and serves to shift a clutch element 84,keyed upon the shaft 42, to move longitudinally thereof and turntherewith. This lever may be locked in adjustment by any suitable means.The clutch element is adapted to engage a coacting clutch element 85,rigidly secured to the bevel gear 48. It is thus seen that when theclutch element 84 is in the lowered position, the gear 48 will be lockedto its shaft.

The shaft 42 projects upwardly beyond the cover 39, into an annularflange 86, formed integral with the cover, the upper portion of theshaft being formed polygonal in cross section, numeral 88 designates agear casing or housing of a wringer, to be described, and this housingcarries a depending annular flange 89, pivotally receiving the flange86, as

clearly shown in Figure 5. This flange 89 is provided at its lower endwith slots 89', preferably four in number, arranged 90 apart, andadapted to receive a sliding bolt 90, carried by the cover 39, andshifted by a handle 91'.

The numeral 99 designates a 'wringer as a whole, secured to the gearcasing 88. This \vringer embodies a pair of rolls 100, suitably drivenby the gears (not shown), in the 88, and these gears are driven by acoupling shaft 101, adapted to engage the polygonal end 87, as shown inFigure 5.

The operation of the apparatus is as follows:

The motor 47 may be set into action by the usual switch, and the shaft42 will be driven. By shifting the clutch element 84 downwardly. thebevel gear 48 will be locked to its shaft, and the drum 71 rotated.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the sub joined claims.
